A process for performing reactions in a liquid-solid catalyst slurry where feed gases pass continuously upward through the slurry bed contained in a reactor vessel and operating at elevated temperature and pressure; convening the gases to liquid and vaporous products; withdrawing the liquid products through a shaped-wire filter element having precise slit openings in the range between 0.5 and 100 microns; and exiting from the bed and then from the top of the reactor vaporous products formed in the slurry and any unreacted gas. The filter element retains in the bed the solid catalyst particles larger than the slit width. The liquid is withdrawn to an accumulator external to the reactor vessel. The accumulator and the liquid chamber inside the filter element have unrestricted venting to the space above the expanded slurry bed. Liquid is withdrawn from the accumulator, while holding a suitable fixed level. The filter system neither plugs nor forms a cake during sustained operation.
